MilwaukeeGo forMajor League fun without the fussLeave your hometown allegiance at the Illinois state line. A game at Miller Park(414-902-4400; tickets 414-902-4000), one of the family-friendliest in the MLB, is all about having a good time. Kids 14 and under (and seniors) get up to 50 percent off most seats for all weekday afternoon games, and the first 2,000 fans ages 12 and under at every Sunday afternoon game get free ice cream. Squirmy young fans can keep busy as soon as the park gates open at the Kids Zone, where there are batting and pitching cages and loads of interactive, baseball-themed activities. Even better: The convertible roof means spring’s unpredictable weather is a non-issue.If there’s timeDiscovery World(500 N Harbor Dr, Milwaukee, WI; 414-765-9966. $17, kids 3–17 $13.) wraps several attractions into one: science and technology, aquariums, a 19th-century schooner reproduction and more.

Indiana Amish CountryGo forAn excuse to unplug If you’ve got tweens or teens who can’t get enough of all those Amish reality shows, intrigue them with a trip to the real deal in Elkhart County, about two hours from Chicago. They’ll likely find a quainter scene than what they see on TV at Amish Acres(1600 W Market St, Nappanee, IN; 800-800-4942. $13, kids 4 and up $5.), which is an 80-acre living museum of sorts, with a restored farmstead, round barn theater offering children’s productions, maple syrup sampling and horse-and-buggy rides.
